Thx in advance. This is an 02 base.

You will need either the Durametric system or access to a PIWIS unit to test the engine compartment fan without taking the car apart to manually test the fan.
The coolant level sensor is located at the bottom of the surge tank in the rear trunk, and can be accessed by pulling the carpet back. The rate of the flashing light also will tell you what is up:
"Four functions of the coolant warning light:
1. Engine coolant level too low -- light flashes slowly (0.5 Hz)
2. Engine compartment temperature too high -- light flashes slowly (0.5 Hz) (engine compartment blower might be faulty)
3. Engine coolant temperature too high -- light is lit; pointer on the right
4. Temperature sensor at water outlet faulty -- light flashes rapidly (1 Hz) ; pointer on the right
